' To` all 'whom it may concern:

Be it known that I, FERDINAND voN MADALER, a' subject of the Austro-Hunga-` rian Emperor, residing at West Drayton, in the county of Middlesex, England, have in- -vented a new and useful Improvement in Film-Carriers, of which the following is a specification.

This invention relates to roll film or strip carriers for kinematograph or like machines of the type described in my co-pending application filed 24th April 1912 under Serial No. 763434:, wherein a carrier, containing a film, may be inserted or removed from the machine to provide a change of subjects or films, without any handling of the filmer strip. According to this invention these carriers, which are primarily intended for use in connection with the projection of posit-ive film pictures, though applicable for taking negative film pictures, comprise a case or guard, preferably of metal so as to render same fireproof7 which contains and protects the film or strip when the latter is not in use and during the various manipulations preceding` its sale and delivery as well as during its use and which adds so little to the ycost of the vfilm or strip that the latter can'be retailed or sold therewith, such holder being adapted for immediate service in the machine without preliminary adjustment, as a mount or supportfor the film. The carrier is furnished with a light shaft situated between and entirely separating the two spool chambers and serves for .the passage of the rays of light. The picture aperture is placed at one end of and coincident with said light ray opening so that a film or the like, can, if it is an exposed one, be projected'by light transmitted through it while contained in the carrier. One of the chambers is also provided in the wall thereof and nearthe picture aperture with a cavity or embayment for housing the means, such as a sprocket wheel for example, for moving the lm band with anv intermittent motion past the picture aperture. Such a case or guard may be a closed one except for the opening through same o1? it may be a framework only if sufficient fortle purpose. If closed it presents the advantage of affording protection to the film from fire, dust, scratching or handling vexcept at the point of the throughway or opening where the fire could be localized as by f gripping rollers.

A carrier or case thus constructed is rendered capable of being operated in a kinematograph or projecting machine of the type referred to by providing it with rollers preferably carried by suitable spindles to support the film such rollers being available from the outside of the casing or guard through means such as a bent pin, spindle, crank, holes or the like for connect-ion with apart of the driven mechanism of the machine. Both rollers are preferably 4so provided lto enable the travel of the film to be reversed. The carrier is thus self-contained; that is to say, it is at all times complete with its various parts consisting o-f film, or strip, rollers, spindles, and means for connection with or engagement by t-he mechanism of the kinematographor like machine, and is adapted to be dropped or inserted easily into the machine so that the film or strip passes over the driving mechanism or sprocket-wheel, or removed from th'e mach-ine without any preliminary operations or adjustment. The carriers which are preferably of metal are made as light in weight and as slight' in bulk asis possible compatible with the requisite strength and rigidity, and further, they are made so thin that they-can be placed in an envelop for postal purposes.

It has been proposed to provide .consecutive yview cameras and projecting apparatus with a number of removable film or picture prepared for use before they are placed in the camera or projecting apparatus but these have formed with them, or carry as a part of them, some of the mechanism of the camera or apparatus such as a part of the film driving means such mechanism, as well as the construction of one of the film rolls, necessitating the box being threaded onor inserted over two projecting driven spindles to give action to the parts in questioni Such a box is necessarily more or less a part of the camera or projecting apparatus as 4it cont-ains some of its mechanism andvis thus not adapted to carry out the'objects of this invention particularly the commercial aspect l of same under which an inexpensive casing or guard is provided protecting the lm during storage, sale or other handling and servino also as a mount for the lm when itis being operated in the camera or other apparatus. It has also been proposed to en- 2 L 1,roo,591

In witness whereof I have hereunto set my. hand in the presence of two subscribing witnesses.
